- They should remove toxins from their bodies.
- They should remove toxins from their body.
I am confused about these two sentences above. I think the first sentence is correct because 'their' means more than one person and the body must be more than one. However, I wonder if their bodies could mean each person has more than one body. The reason I ask this question is because of the sentence below.
Frogs spend most of their life in water.
If 'their bodies' is correct, Should 'their life' in this sentence be 'their lives' because 'frogs' is plural?
